electromagnetic waves

electromagnetic spectrum

family of waves that travel through a vacuum at a 3X10^8m/s

magnetic field

force field in which a magnet, current carrying wire or moving charge experiences a force

electromagnetic wave

transverse wave travelling through space as vibrations of elctric and magnetic waves

speed of light in a vacuum

3X10^8 m/s

light travelling from less to more dense mediums

speed decreases and frequency remains the same…wavelength increases

radiowaves

>10^6 to 10^-1

microwaves

10^-1 to 10^-3

infrared

10^-3 to 7X10^-7

visible light red to violet

7X10^-7 to 4X10^-7

ultraviolet

4X10^-7 to 10^-8

x-rays

10^-8 to 10^-13

gamma rays

10^-10 to 10^-16

electromagnetic waves as transverse waves

electric and magnetic waves vary at right angles to each other, and at right angles to the direction of which the wave is travelling

electric field

force field in which an electric charged particle experiences a force
